# Struct hashbrown::raw::inner::ProbeSeq

``````struct ProbeSeq {
pos: usize,
stride: usize,
}``````
Expand description

Probe sequence based on triangular numbers, which is guaranteed (since our table size is a power of two) to visit every group of elements exactly once.

A triangular probe has us jump by 1 more group every time. So first we jump by 1 group (meaning we just continue our linear scan), then 2 groups (skipping over 1 group), then 3 groups (skipping over 2 groups), and so on.

Proof that the probe will visit every group in the table: https://fgiesen.wordpress.com/2015/02/22/triangular-numbers-mod-2n/
